Question

Using the slope and the y-intercept, graph the line represented by the following equation. Then select the correct graph. 2x - y + 4 = 0

Answer 1

Answer:

slope =2  and y intercept =4

Step-by-step explanation:

Using the slope and the y-intercept, graph the line represented by the following equation.

2x - y + 4 = 0

To get slope and y intercept we write the equation in the form of

$y=mx+b$ where m is the slope and b is the y intercept

$2x - y + 4 = 0$, solve for y

Subtract 2x on both sides

$- y + 4 = -2x$

Subtract 4 on both sides

$- y = -2x-4$

Divide both sides by -1

$y =2x+4$

Slope =2  and y intercept = 4

now start graphing at y intercept (0,4)

for slope we move up by 2 units and right by 1 units

the graph is attached below

Answer 2

Go up to 4 on the y axis, and then go up 2 and over 1, then graph.
